325 Watt
MONO HALF CELL SOLAR MODULE

Features

High power output
Compared to the normal module, the power output can increase 5W-10W
Excellent weak light performance
More power output in weak light conditions, such as haze, cloudy, and morning
Extended load tests
Module certified to withstand front side maximum static test load (5400 Pascal) and rear side maximum static test loads (3800 Pascal) *
High PID resistant
Advanced cell technology and qualified materials lead to high resistance to PID
Suntech current sorting process
System output maximized by reducing mismatch losses up to 2% with modules sorted & packaged by amperage
Withstanding harsh environment
Reliable quality leads to a better sustainability even in a harsh environment like desert, farm, and coastline

Certifications and standards: IEC 61215, IEC 61730, conformity to CE

Trust Suntech to Deliver Reliable Performance Over Time

  • World-class manufacturer of crystalline silicon photovoltaic modules
  • Unrivaled manufacturing capacity and world-class technology
  • Rigorous quality control meeting the highest international standards: ISO 9001: 2008, ISO 14001: 2004, and ISO17025: 2005
  • Regular independently checked production process from the international accredited institute/company
  • Tested for harsh environments (salt mist, ammonia corrosion, and sand blowing testing: IEC 61701, IEC 62716, DIN EN 60068-2-68)***
  • Long-term reliability tests
  • 2 x 100% EL inspection ensuring defect-free modules

Industry-leading Warranty based on nominal power

  • 97.5% in the first year, thereafter, for years two (2) through twenty-five (25), 0.7% maximum the decrease from MODULE’s nominal power output per year, ending with 80.7% in the 25th year after the defined WARRANTY STARTING DATE.****
  • 12-year product warranty
  • 25-year linear performance

Special Cell Design

The unique cell design leads to reduced electrodes resistance and smaller current, thus enables a higher fill factor. Meanwhile, it can reduce losses of mismatch and cell wear, and increase total reflection.

IP68 Rated Junction Box

The Suntech IP68 rated junction box ensures an outstanding waterproof level, supports installations in all orientations, and reduces stress on the cables.
High reliable performance, low resistance connectors ensure maximum output for the highest energy production.
